OK,
Quick Question....
I have the 2mm solid corner seals from Atkins and they look to be machined on one side and ground to a shiny smooth surface on the other side.
According to Atkins, Mazda, and many other builders I have spoken with, corner seals are recommended to ONLY be used in ONE DIRECTION...that being the smoother, or ground/polished side toward the plate, and the rough or machined side toward the corner seal spring.
So....do you believe that these can be used on either side, or should they only be filed and used in the intended orientation? The attached picture shows the machined one on the left, and the smooth ground side on the right.....
I hope that made sense...
O..and one other question......
What is your opinion on the use of Vaseline for engine assembly? When the Rotors are built first, they are bagged up and used later (Like a week or so). Can Vaseline be left on Atkins Viton, OR the OEM Mazda oil seals for that long, or is this a problem?
From my understanding and experience, I have not seen an issue with this, but I thought I would ask your opinion and experience. I use Hylomar for the coolant and gas seals, and the o-rings on the rotor housings, but Vaseline on ALL the rotor parts to keep them from falling apart. I also install the Apex seals and springs in the rotor when it is placed in the rotor housing when assembling on an engine stand and I do not use glue anywhere....
OK..I think that is enough for now...
Thanks for all the good info though Ito!

Atkins has a new design on the solid 2mm corner seals. no more flip over deal. at this point u need to check for proper clearance.
Hey Judge...
Those Corners in the pic ARE the new 2mm from Atkins. They are different on each side...one is machined and one is ground...that is why I was wondering about the flip over....maybe I got some of the last of the old type?
Also, I am getting WAY too much clearance on the side seals and I think I am going to go ahead and get a new set and clearence them out instead of trying to fit used garbage.

Also, after closer inspection...these Atkins corner seals are ground completely flat on the side that contacts the plate surface, and the spring contact side has the sharp edge taken off (bevelled).
Shiney smooth side has a sharp edge, and the slightly rougher machined side has a rounded edge.

I have a question about sanding down the apex seal to rotor groove clearance. Do you sand down the apex seal and the groove? Also what do you use to sand them down? My 3mm atins apex are a little tight.. Need the .002 clearance..

you file the rotor groove. takes very little material off the rotor groove
